Access Control Mechanism for Multi-user Data Sharing in Social Networks

Online social networks (OSNs) have analyses large growth in recent years and become a saturation for hundreds of millions of Internet users. These OSNs offer to enforce attractive means for digital social interactions and information contribution, but also increase a number of security and privacy issues. Right to use manage mechanism is provide to restrict shared data, they currently do not provide any mechanism to minimize problem of multiuser shared data. To this end, we propose an approach to enable the protection of shared data associated with multiple users in OSNs. We gives a platform to user to share their data in secure manner. We also discuss a proof-of-concept prototype of approach as part of a framework on social network and provide usability study and system evaluation of our method.
